The breather issues are well-known and documented, and despite the small sample I’ve worked with/owned, there doesn’t seem to be any consistency of when you can expect it to occur. It seems like the breather tube that goes into the back of the engine will clog up around 100k or thereabouts, but the rest of the system doesn’t seem to clog up on a predictable basis. I suspect that’s probably due to differences in how the engine has been driven, the type of oil, etc., etc.
